The “Pressure” parameter corresponds to the amount of breath pressure applied to a
reed or mouthpiece, or the speed of the bow applied to a string. Pressure variations affect
both volume and timbre. The “
Controller ” parameter specifies the controller to be
used for pressure control. When set to “
off
” maximum pressure is applied at all times.
• Please note that accurate keyboard pitch is produced only at maximum pres-
sure.
• The actual pressure value applied to the VL7 tone generator is the product of
the pressure from the controller and that from the pressure envelope (

●
Depth
≤
-127 … 127.
Sets the amount of variation produced by the controller assigned to pressure. The
higher the value the greater the variation. Positive values cause an increase in pressure in
response to higher controller values (e.g. increased breath pressure or higher modulation
wheel position), while minus values cause a decrease in pressure in response to higher
controller values. The “
Depth
” setting is reflected in the graph to the right of the param-
eters — the horizontal axis represents the controller value and the vertical axis represents
pressure.
●
Curve
≤
-16 … 16.
Determines the relationship between the controller value and pressure. When set to
“ 0 ” the relationship is linear. That is, a change in the controller value produces a corre-
sponding change in pressure. As the curve value increases the lower end of the controller
range has relatively little effect on the sound while higher controller values produce more
dramatic changes. Negative curve values have the opposite effect: the sound changes
dramatically at low controller values while higher values produce relatively little effect.
The “
Curve
” setting is reflected in the graph to the right of the parameters — the
horizontal axis represents the controller value and the vertical axis represents pressure.
